In this study, differences in the respiratory patterns
of volunteers and patients were analyzed and reported
using a respiratory self-navigated approach.
Furthermore, a novel iterative approach for
self-navigation was developed and described. This
technique has the advantage of being independent from
the choice of a specific respiratory reference position
for motion correction, and showed improved performances
with respect to a more standard approach when
respiratory motion correction was applied to irregular
breathing patterns of patients.
